Bondhus 5/16″ nut driver used for tightening down nuts cleanly, without scuffing up the nut or damaging your guitar’s finish like pliers and wrenches can do.  This nut driver comes equipped with a hexagonal upper shaft that can be used with pliers or a wrench when extra torque is needed and the non-slip, ergonomic, anti-roll handle offers a comfortable feel and prevents the tool from rolling off your bench.   A handy, time-saving tool recommended for any repair tech or luthier!  The Bondhus 5/16″ nut driver is commonly used to tighten or loosen Gibson® truss rod nuts.
